Here:
'...No, the Kyoto Initiative would not have been good for this country or our economy, and as soon as you manage to get the majority of the world to
our pollution control standards, come back and talk to us.'
So, you've never been here, you just assume it must be pretty filthy? Oh, I see now.
You surely want to make a real issue about that fact, conveniently ignoring
you still didn't support any of your arguments with information. I
did, like it or not.
Besides: do you know the Occam's Razor?
'one should not increase, beyond what is necessary, the number of entities required to explain anything'
...then assume the following (and I don't think it's going to be much difficult):
a) Your cities are populous...
b) Your numbers of cars per capita are high as well. There are an huge number of cars in cities.
c) Most of the cars are big ones. Big cars are heavy cars, and as so, consume lots of fuel.
d) Fuel combustion is one of the most air contaminating factors.
a + b + c + d = great clouds of NOx, CO, CO2.
As you see the air over the cities is clear, and you are *actually* there, we must assume you say the truth, but that leaves us with the problem of
where is all that contaminated air. We have the following options:
a) Contamination clouds are so dense those not get to the air, but precipites over the streets.
b) Great winds take the cloud far away before it actually condenses.
c) Most citizens are so used to see the air polluted, they even don't realize it's polluted, but in its normal state.
Please, pick one.
...and don't forget to support your conclusions with
some info. Thanks for your cooperation.
We are not in China , so, we can speak.
